A touch of winter weather will likely sweep through the region this weekend, sprinkling the valley and High Desert areas while gracing the San Bernardino Mountains with some snow, according to a weather forecaster.

A low pressure system is passing over the central part of the state, and its bottom trough will hover over the Inland Empire for a short time.

The brunt of the storm is expected to hit tonight into Saturday morning as snow is expected to dust elevations above 5,000 feet, according to Jimmy Taeger, a meteorologist with the National Weather Service. He said one to three inches of snow is expected from 6,000 to 7,500 feet and up to four inches may dump on peaks above 7,500 feet.

Along with the snow, high winds out of the southwest are being projected for mountain areas and the High Desert, according to Taeger. They’ll likely blow at speeds of about 30 to 45 mph with gusts topping 60 mph tonight and tapering off Saturday, Taeger said.

The valley region, including Ontario, San Bernardino and Redlands, won’t see much precipitation, maybe a tenth of an inch, according to Taeger, but temperatures will be lower than average and clouds will move in today.

Temperatures on Saturday are expected to be about 15 degrees below average in Ontario, topping out in the mid-60s. Highs in the upper 50s will be 15 to 20 degrees lower than average for this time of year in the High Desert.

By Sunday, the weather system should pass, skies will clear and the days should return to more average temperatures, according to Taeger.

“The system is expected to move through Saturday morning, so we should have conditions starting to improve Saturday afternoon,” he said.
